CudaText is a code editor with a simple, tabbed interface and side-panels. Includes split view, code folding, hotkeys, theme support, color picker and more. The program supports 190+ syntaxes and add-ons written in Python, as well as some IDE features if plugins are used.

The program is cross-platform with clients available for Mac and Linux. Note that settings are modified via text config files (JSON format) in place of options dialogs.

What is good is that CudaText has text/raw/hex viewer - from the Universal Viewer app. For files which cannot be edited [huge files]. It can viewer, like Universal Viewer, files of any size, e.g. 4Gb. But not edit, only view.

Includes support for PHP, ASP, JavaScript and CSS/HTML editing with integrated preview.

The latest version (v5.2.1) produces an exeption and refuses to start on my machine (Win 8.1 x64 without .NET & VC++ runtimes). Perhaps the system requirements changed? Nothing mentioned in the changelog.
